Paleoceanography and Paleolimnology

  • Mark Brenner is a limnologist and paleolimnologist with special interests in tropical and subtropical lakes and watersheds. He uses sediment cores from the bottoms of lakes to reconstruct the history of aquatic ecosystems and their drainage basins. (email:
  • James Channell applies magnetic polarity stratigraphy to the generation of geologic time scales. Studies of past climate face the challenge of global millennial-scale correlation of climate-proxy records, that usually cannot be provided by the stable isotopes, biostratigraphy or radiometric ages. Variations in the intensity of the geomagnetic dipole field, when recorded in sediments and used together with more conventional stratigraphic tools, appear to provide a means of global correlation appropriate for the study of rapid climate change.

  • Jason Curtis is a paleoclimatologist who focuses on Holocene and latest Pleistocene climate and environmental changes. Much of his work involves stable oxygen and carbon isotopes preserved in carbonate microfossils from tropical lake sediments. Currently he is analyzing material from the lakes in the Amazon basin, Crete, Mexico, and Guatemala. (email:
  • John Jaeger examines the role of glaciomarine processes in high-latitude marine sedimentation, landscape evolution, and modern climate change reflected in glacier dynamics. A range of sedimentological, mineralogical, and chronological tools are used to quantify the role of glacial processes affecting margin sedimentation in the Gulf of Alaska. (email:
  • Ellen Martin uses radiogenic isotopes in marine sediments to study the relationship between ocean circulation and climate over a wide range of time scales from the Permian to the Pleistocene. In particular, Martin is focusing on the effects of major gateway events such as the opening of the Drake Passage and the closure of the Isthmus of Panama. (email:

What is this view?

You are using a dynamic assistive view of the University of Florida site. It has all the same data and features of the original site but formatted just with assistive users in mind. It has links and content reorganized to aid assistive users and has controls at the bottom under assistive options that allow you to control key aspects such as font size and contrast colors etc.
This is not a separate text-only site, it's a dynamic view that uses unique technology from Usablenet to give assistive users better, more accessible access to the same content and features as all users that use the graphic view of the site.
